This device uses infrared technology to help find veins
How? Well it works in a similar way to pulse oximetry. Haemoglobin in the blood absorbs infrared light. When AccuVein’s device is held above the skin, it can detect the difference in the haemoglobin concentration between the veins and surrounding tissue, projecting a map of the veins on the skin above them. Locating the point of needle placement is suddenly simplified for phlebotomy techniques.
This technique has been used for some time when drawing blood from newborns, but is now becoming more frequently used in adults. Those with particularly difficult venous access (DVA) can include:
- The elderly;
- Dark-skinned patients, whose veins may not be visible;
- Obese patients, whose veins may not be visible or palpable;
- Patients having many diagnostic or therapeutic intravenous procedures;
- Burn victims;
- Agitated or restless patients;
- Oncology patients on chemotherapy;
- Other patients with chronic diseases;
- Drug abusers.
i’ll take all of them
An illegal trader was arrested Tuesday in Cameroon in possession of 4 gorilla heads and 16 hands and legs, following a joint operation between Cameroon law enforcement officials and the Last Great Ape Organization (LAGA). This brings to 34 the number of great apes lost to traders in ape parts in Cameroon in 2014. For more information, visithttps://www.facebook.com/ofir.drori?fref=photo.
Chioggia beets! These are my favourite variety of beet to grow. They taste very similar to regular red beets, in my opinion. Also really easy to grow where I live. This beauty is going in my salad tonight! 🌿 (at Sunshine Coast, BC)
This light-year-long knot of interstellar gas and dust resembles a caterpillar on its way to a feast. But the meat of the story is not only what this cosmic caterpillar eats for lunch, but also what’s eating it. Harsh winds from extremely bright stars located 15 light-years away from the knot towards the right edge of the image, are blasting ultraviolet radiation at this “wanna-be” star and sculpting the gas and dust into its long shape.
The caterpillar-shaped knot, called IRAS 20324+4057, is a protostar in a very early evolutionary stage. It is still in the process of collecting material from an envelope of gas surrounding it.
